4. ELEPHANT CASUALTIES ON RAILWAY LINES
A total of 186 elephants were killed after being hit by trains across India between 2009-10 and 2020-21, according to the Ministry of Environment, Forest and Climate Change (MoEFCC).
About:
- Assam accounted for the highest number of elephant casualties on railway tracks (62), followed by West Bengal (57), and Odisha (27). Uttar Pradesh saw just one death.
Measures taken to avoid elephant casualties on railway lines
- A Permanent Coordination Committee was constituted between the Ministry of Railways (Railway Board) and the MoEFCC for preventing elephant deaths in train accidents.
- Clearing of vegetation along railway tracks to enable clear view for loco pilots, setting up underpass/overpass for safe passage of elephants, regulation of train speed from sunset to sunrise in vulnerable stretches, and regular patrolling of vulnerable stretches of railway tracks are among other initiatives the Ministry has undertaken.
- The MoEFCC released ₹212.49 crore to elephant range States under Centrally Sponsored Schemes (CSS) of Project Elephant to protect elephants, their habitat and corridors, to address man-elephant conflicts, and for the welfare of captive elephants, between 2011-12 and 2020-21.

5. RED-EARED SLIDER
A ‘cute’ American turtle popular as pet is threatening to invade the natural water bodies across the Northeast, which is home to 21 of the 29 vulnerable native Indian species of freshwater turtles and tortoises.
About:
- Between August 2018 and June 2019, a team of herpetologists from the NGO ‘Help Earth’ found red-eared sliders in the Deepor Beel Wildlife Sanctuary and the Ugratara temple pond — both in Guwahati.
- The red-eared slider (Trachemys scripta elegans) derives its name from red stripes around the part where its ears would be and from its ability to slide quickly off any surface into the water.
- Native to the U.S. and northern Mexico, this turtle is an extremely popular pet ... But on the flip side they grow fast and virtually leave nothing for the native species to eat.
- Much like the Burmese python that went to the U.S. as a pet to damage the South Florida Everglades ecosystem, the red-eared slider has already affected States such as Karnataka and Gujarat, where it has been found in 33 natural water bodies.
- But more than elsewhere in India, preventing this invasive species from overtaking the Brahmaputra and other river ecosystems in the Northeast is crucial because the Northeast is home to more than 72% of the turtle and tortoise species in the country, all of them very rare.

6. ‘MICE RAIN’ IN EASTERN AUSTRALIA
The government of New South Wales (NSW) in Australia has extended a support package of $50 million to farmers to deal with a devastating mouse plague that has affected farmers, community members and residents.
About:
- To control the plague, the government has now authorised the use of an otherwise outlawed poison called
- The current plague is being called one of the worst plagues in decades and started being reported around mid-March in Australia’s eastern states. In some places, residents of affected areas reported mice falling out from roof tops causing “mice rain”.
Reasons
- Researchers attributes the plague to an unusually abundant grain harvest, which caused a surplus of mice earlier in the season.
- Add to this the fact that mice have a short breeding cycle (a pair of breeding mice can give birth to a new litter every 21 days or so) and are not very choosy about food. Rodents (which includes rats and mice) are the second most successful mammals on the planet after humans.
Important Info :
How does a plague of this scale affect people?
- Rodents are capable of destroying food grains and can cause widespread damage to domestic households, commercial businesses, farms, manufacturers and livestock. Further, rodents can not only gnaw through materials but can also ruin supplies by excreting on them.
- Rodents can also cause diseases such as leptospirosis and typhus fever. They can also carry fleas or ticks that can harm pets and humans.

9. IRON DOME SYSTEM
The Iron Dome aerial defence system intercepted a Hamas Unmanned Aerial Vehicle (UAV) that crossed from Gaza into Israel, Israeli Defence Forces (IDF) said on social media
About:
- Iron Dome is a multi-mission system capable of intercepting rockets, artillery, mortars and Precision Guided Munitions like very short range air defence (V-SHORAD) systems as well as aircraft, helicopters and Unmanned Aerial Vehicles (UAV) over short ranges of up to 70 km.
- It is an all-weather system and can engage multiple targets simultaneously and be deployed over land and sea. Iron Dome is manufactured by Rafael Advanced Defence Systems and has been in service with Israeli Air Force since 2011. The radar system was developed by Elta.
- Its development was prompted after a series of rocket attacks on Israel by Hezbollah and Hamas in the 2000s.
How does it work?
- An Iron Dome battery consists of a battle management control unit, a detection and tracking radar and a firing unit of three vertical launchers, with 20 interceptor missiles each.
- The interceptor missile uses a proximity fuse to detonate the target warhead in the air.
- The Iron Dome is deployed in a layered defence along with David’s Sling and Arrow missile defence system which are designed for medium- and long-range threats.
- The I-DOME is the mobile variant with all components on a single truck and C-DOME is the naval version for deployment on ships.
Important Info :
Benefits
- One of the system’s important advantages is its ability to identify the anticipated point of impact of the threatening rocket, to calculate whether it will fall in a built-up area or not, and to decide on this basis whether or not to engage it.
- This prevents unnecessary interception of rockets that will fall in open areas and thus not cause damage, the paper states. The system has intercepted thousands of rockets so far and, according to Rafael, its success rate is over 90%.
